Lets encrypt renewal problems

Reporting an Issue
1

Hey folks, just wondering if anyone can help out point me in the right direction. I am getting emails to me about lets encrypt failing renewal but things seem okay with my certificate?

I am getting this error in my email like every night

Cannot validate the certificate authorization - #0 /usr/share/vitalpbx/www/modules/certificates/Types/LetsEncrypt.php(0): modules\certificates\Types\LetsEncrypt->_build()
#1 /usr/share/vitalpbx/scripts/lets_encrypt(0): modules\certificates\Types\LetsEncrypt->build()
#2 {main}

It tells me to check logging under/var/log/vitalpbx/. When I check there is nothing.

So just wondering if anyone had some advice what I could try.

Let’s Encrypt requires port 80 open for incoming requests, and additionally, requires multiple IPs whitelisted to be able to renew Let’s Encrypt certificates.

I have port 80 open and allowed to anywhere. This has only recently popped up and never had issues before.
